SPECIFICATION forming part-of'Letters Patent No. 617,743, dated January 17, 1 899.

. Application filed February 16,1898. Serial No. (910,494. (no an.)

To all whom, it may concern: Beit known that I, GEORGE HAYES, acitizen of the United States, and ag psiden't ofthe city, county, and State of New ork, have i n vented a new and useful lmprovemelnt/ in Wheels for lfiicycles and other Vehic es, of which the following is a specification. My improvement relates to the'central portion of the whee1;.and my invention consists :o of a construction wherein-the axle-hub is re siliently sustained centrally within an encircling spoke-nave by are springs integral and in combination with spiral coils of approximately tubular shape encircling spi'n- 4.5..dlesnonrcrossrrods. certain of which extend between end flanges of the axle-nun and othersextending between cheeksorend disks of the spoke-nave, all as hereinafter more fully described,and pointed out in the claims, reference being had to the accompanying drawings, in which g Figure 1 represents a vertical s ction of the s axle-hub, axle, and spindles with insideface,

' the one end flange of the axle-hub and inside. 2 5 face of the one end check or disk of the spokenave 'with one form of. are springs combined fwith tubular coils; Fig. 2 is a perspective of' a portion of springs alone.' Fig. 3 is a face elevation of one of the tubular coils with portions of arc extensions therefrom. Fig. 4 is an elevation of a spindle or cross-rod. Figs.

-5 and 6 are sectional figures corresponding with that of Fig. 1, illustrating changes as to the arrangement of springs, they having been brought wholly within the periphery of the spoke-nave. Fig. 7 is a view corresponding tothat of Fig. 1, illustrating a change or modification in arrangement of springs, in this case reversed and arching inward, bringing the axle-hub against or upon the apex of each arch, the arch being composed of two are springs joining with one tubular spring -interiorly. Fig. 8 is a view of a tubular coil, barrel-shaped, it having convexity lengitndinally, otherwise corresponding to those of the previous figures, whichare cylindrical. Fig. 9 is a perspective view of the wheel-center, axle, axle'hub, and spoke-nave with are springs arranged as in Fig. 7 and with the bar.-

5'0 rel-shaped tubular coils of Fig. 8. Fig. 10 is an elevation of a tubular spiral spring, formed of two coils interwovemone threaded into the other. Fig. 11 is a perspective view of a tuzbular spiral spring formed double, as that of Fig. 10.

Dotted lines in Figs. '10 and 11 indicate 'shapeof springs when two spirals like that B indicates the spoke-nave, made as two centrally-apertured checks or disks secured together at proper distance apart by crossrods B, the disks encircling the axle-hub and the hub and nave connected by a system of metal springs, est-follows."-

0 indicates certain spiral coils sleeved upon the cross-rods B of the spoke-nave, and D indicates other spiral coils sleeved upon crossrods extending parallel to the axle-hub, between flanges thereof at A or rings as flanges threaded thereupon, each of the spiral coils being constructed in tubular form and each encircling a cross-rod, which serves a'sa spindle therefor.

E indicates arc-shaped continuance of the metal integral with the coils, as connectionlinks or stretches between such coils, as

in securing resiliency between the spokenave and axle-hub.

In Fig. 1 the arcs are so formed as to extend beyond the periphery of the spoke-nave.

In Figs. 5, 6, and 7 the arcs are shown as hub is essentially within arches and resting upon the apex of each.

The arrangement of springs in Figs. 5 and 6, though different,.produces, essentially, the

same efiect. The arrangement of Fig. 1 brings the axle-hub to rest, essentially, against the bases of the area and produces as to the spoke- I oo shown. The arcs act auxiliary to the 'coilsof at the proper distance apart, which permit of their faces sliding readily against (with out binding) the flanges A of the axle-hub, which flanges serve to guide the movement and also to prevent any lateral movement.

The end spirals of the tubular coils, whether cylindrical or barrelshaped, encircle the washers H, and those between are thus held from direct contact with the spindle which they encircle, enabling ready contraction and expansion of the spirals. The Wind of the spirals is formed somewhatopen to also allow freedom of movement and afford slight twist, whereby ellfective resiliencyissecured therein. The resiliency is supplemented by the spri n ging of the arcs E by their own natural reaction and also by the extended tightening, and consequent resistance, of the coils as the arcs give under pressure produced by weight carried or shock received. v In Figs. 10 and 11 a tubular coil is shown wherein two spirally-wound wires are threaded together, which when placed npona spindle operate like those before mentioned. In this formation the double arrangement constituting two sets, as in Fig. 9, would not be necessary and the tubular coil would extend the length of the spindle upon which it was placed, and each coil so formed would have four are ends or stretches, as links, extending to other coils after the manner shown. This arrangement has, perhaps, a m ore er n able effect and is applicable to either the cylindrical or barrel shaped springs.

XVhat I claim as new, and desire to secure by Letters Patent, is-

1. A. wheel for bicycles and other vehicles formed with a hollow or skeleton spoke-nave, constituted as two disks, centrally npertu red,

arranged parallel and connected by cross-rods 46 p or spindles, with within the same and extending through the disk-apertures, an axle-hub provided with annular flanges with which the disks of the spoke-nave are in facial contact, and between which extend cross-rods or spindles parallel to those of the spoke-nave, upon each of the spindles of spoke-nave and axlehul), a tube or cylindrical wind of wire, as a spiral spring, with stretches or continuations of the wire extendingin the arc shape to other spiral springs, thus connecting the springs of the spoke-nave with those of the axle-hub, whereby a resilient action is secured, essen tially as set forth.

f 2. In a wheel for bicycles and other vehicles constructed with a special spoke-nave encircling an axle-hub, the series of arc-shaped springs, continuationsv from tubular coils upon spindles of the spoke-nave, extending beyond the periphery of the spoke-nave and.

converging inward toward the axle-hub, as lines radiating therefrom and connected integrally with tubular coils upon spindles of the axle-hub, essentially as set forth.

3. In a wheel fol-bicycles and other vehicles, a special spoke-nave encircling an axle-hub,

each provided with series of cross-rods on spindles, with upon each spindle a spirallycoiled tubular spring of wire formed between its lateral extremities with convexity, the springs of axlehub and spoke-nave connected by stretches-of wire integraltherewith, essen tially as set forth. I
